2.2.10 C&P Head Type DLM2 with 12/6 Segments
Depending on the configuration, the Siplace X machines can be equipped with C&P 12 or 6-seg-
ment heads of type DLM2.

2.2.10.1 Steps When Picking Up and Placing Components
– A PCB moves into the placement area of the PCB conveyor and will be clamped.
– After the fiducial measurement, the C&P head picks up components from the feeder modules.
– The components are measured below the component camera and rotated into the correct
placement position (angle) in the DP station.
– The component is placed in star station 1.
2.2.10.2 Position and Function of the Individual Star Stations (see Fig. 2.2 - 21)
Star station 1 2
Pick-up cycle
The nozzle is lowered onto the component. The valve positioning unit opens the vacuum circuit to
the nozzle, the nozzle picks up the component and removes it from the feeder module.
Placement cycle
The nozzle, together with the component, is lowered onto the PCB that has been moved into
place. The valve positioning unit closes the vacuum channel to the nozzle. A short burst of com-
pressed air (air kiss) detaches the component from the nozzle and places it on the PCB.
Reject cycle
The valve positioning unit closes the vacuum channel to the nozzle. Defective components are
detached and discarded from the nozzle with a short burst of compressed air (air kiss).
Star station 3 (only used for the HS60 and S27 HM machines) 2
Note:
The HF- and Siplace X machines do not use star station 3 " reject component", as this function is
performed in star station 1.
Star station 7 2
The component is optically centered.
Star station 9 2
Pick-up cycle
The nozzle is rotated to the pick-up position.
Placement cycle
The component is rotated into the correct placement angle.

The optional "presence" and "height" of the component at the nozzle is checked by the compo-
nent sensor.
